Analygas® Systems Model 45 is a combustible gas monitor that supplies a 4-20mA signal proportional to the gas concentration.


It is used in conjunction with our Model 30,

40 or 41 multipoint readout units.

Alternatively, it can be interfaced with a computer or other data acquisition system.

The Model 45 protects property from potential fire and explosion.

Analygas® Systems Model 45 is a wall mounted

gas monitor which utilizes catalytic pellistor technology to detect combustible gases.


The Model 45 can measure gas concentrations

up to 100% LEL.


The signal output is a linear function of gas concentration. The standard 4-20mA output

format will interface with almost any data

acquisition and control unit.
